Evidence – Ballistics certificate

Where a defendant was convicted, after a jury-waived trial, of carrying a firearm without a license and possessing a firearm without a firearms identification card, the judgments of conviction must be reversed because a ballistics certificate was introduced without accompanying testimony from the ballistician who created it, in violation of Melendez-Diaz v. Massachusetts, 129 S. Ct. 2527 (2009).
